Asthma is a condition characterized by recurrent breathlessness, cough or wheeze caused by variable or intermittent narrowing of intrapulmonary airways [ 13. All asthmatic individuals have hyper-responsive intrathoracic airways and because of this most experience acute attacks of bronchoconstriction at times. A great deal of work has been done to understand this hyperresponsive state of the air...
The inter-relationship between the perception of bronchoconstriction, bronchial hyper-responsiveness and temporal adaptation in asthma is still a matter of debate. In a total of 52 stable asthmatic patients, 32 without airway obstruction ¿forced expiratory volume in 1 s (FEV(1))/vital capacity (VC) 84.1% (S.D. 7.9%), and 20 with airway obstruction [FEV(1)/VC 60% (4%)], we assessed the perceptio...
BACKGROUND Assessing bronchial hyper-responsiveness (BHR) is a main diagnostic criterion of asthma. Provocation testing is not readily available in general practice, but peak expiratory flow (PEF) is. Several guidelines promote the use of PEF variability as a diagnostic tool for BHR. This study tested the agreement between histamine challenge testing and PEF variability, and the consequences fo...
Passive Smoking, Pulmonary Function and Bronchial Hyper-responsiveness among Indoor Sanitary Workers
in this paper rst we de ne the notions of positive implicativehyper mv -ideals of types 1,2,3 and 4 in hyper mv -algebras and we investigatethe relationship between of them . then by some examples we show that thesenotions are not equivalent. finally we give some relations between these notionsand the notions of (weak) hyper mv -ideals and (weak) hyper mv -deductivesystems of hyper mv -algebras.
